In addition, some notebooks, win7 systems, computer users, the notebook battery factory will be removed, put aside, this will take the battery down storage, it will also damage the battery, resulting in laptop battery life is getting worse.
Reason analysis:The reason causing most of laptop batteries this phenomenon is due to laptop battery aging or daily maintenance caused, for example, a lot of friends laptop battery, the battery will often to run out, until the computer automatically shut down, it is easy to damage the battery.

Replace the power adapter! As long as the output of the number of volts and the same number of adapters can use, dozens of yuan.But there will also be a power adapter intact, laptop DC input interface circuit has a problem, there is such a situation, only repair!
The possibility of computer hardware failure is relatively large, because the battery down plug notebook can also work, but through when you say no battery, it is also possible that the problem of battery, suggest you go to the computer store for a set of his power to try, no effect to check the hardware, so as to find the key of the problem, I hope to help you
Concrete solution:1, first check whether the notebook battery settings disable battery charging, and other notebook battery management software also disable charging function, we can check;2, may also be because the battery for a long time did not lead to poor contact where, it is recommended to open the notebook clear ash, the power line plug, battery, also may solve.3, if the inspection settings no problem, then most of the notebook win7 system battery internal control circuit or the core problems, need to take care of.4, when some laptop batteries use for a long time, excessive discharge, resulting in 0%, available power is switched on without charge, late repair, repair will also appear even if life and life is not long, the best advice to buy a new laptop battery for it.
